in the opposite direction by means of fingcry pieces.

One object of the invention is to produce an eye-glass mounting' of the kind above referred to which shall be of simple and compact construction, and particularly in which f the spring by which the nose-guard lever is controlled is, to a large extent, concealed within and protected by the body of the mounting.

A second object of the invention is to produce a mounting in which the spring is se formed and arranged as to serve as a pivot to retain the nose-guard lever in place in the body of the mounting, and thus dispense with the pivot-screw or pin usually employed for this purpose.

A third object of the invention is to produce a mounting in which the nose-guard levers are pivoted within the body-portions of the mounting in a secure manner, and in which any movements ot the nose-guard levers transverse to their pivotal movements are etfectively prevented.

To the above ends the invention consists in an eyenglass mounting in which the noseguard levers are mounted between upper and lower parallel portions of the mountings, these parallel portions or body members closely embracing and engaging the upper and lower surfaces ot' the nose-guard levers so as to provide wide, flat bearing surfaces positively controlling the movements of the noseguard levers, so as to avoid dependence upon a pivot-pin or screw for this purpose.

The invention consists further in an eyeglass mounting in which the springs are provided with coiled portions located partly or wholly within pertorations in the body-portions, or in both the body portions and the nose guard levers, in the manner hereinafter described and as delined in the succeeding claims.

In the drawings :-Figure 1 is a rear elevation of a part of an eyeglass mounting embodying the present invention, the noseguard lever being shown in section on the line 1-1 in Fig. 2; Fig. Q is a sectional elevation on the line 2-2 in Fig. l; Figs. 3 and L1 are views corresponding to Figs. 1 and 2, but showing a modified form ot` the invention; and Fig. 5 a view similar to Fig. 2, showing a second modification. Y

Figs. 1 and 2 show the lens-clips 5, the lens-straps G, and a portion oit the lens 7 and the bridge 8 of a pair ol eye-glasses, all of which may be oit' any ordinary or suitable form. In accordance with the present invention, however, the body ot' the mounting is provided with upper and lower members 9 and 10, respectively, and with a flat noscguard lever 11 pivotally mounted between these members, the lever being closely embraced thereby so as to be restricted to pivotal movements in a horizontal plane. The nose-guard lever tcrn'iinates in trout in the ordinary finger-piece 1Q by which the noseguards may be moved apart in allixing ofremoving the eyeglasses.

In the construction of Figs. 1 and 2 the nose-guard lever is secured in placeby means ot a pivot-screw 13 which is screwed into a threaded hole in the upper member 9 and passes loosely through a corresponding perforation in the nose-guard lever. The lower member 10 is also perforated concentrically with the screw 13, this perforation being substantially larger in diameter than the body ot' the screw. The spring by which the nose-guard lever is controlled comprises a coiled portion 14, and bont ends 15 and 16 which are adapted, respectively, to engage the nose-guard lever and the body ot the` mounting to control the noseguard lever in the usual manner. In accordance with the present invention, however, the coiled portion 14 of the spring is located principally within the perforation in the member 1() so as to be substantially concealed and protected by the body ot the mounting, and the spring is secured in this position by its bent end 1G, which lies above the member 10 so as to prevent withdrawal ot the spring except when it is bent for this purpose. rlhis arrangement produces, as is apparent from the drawings, a very compact and neat mounting, and it has greater strength and Figs. 3 and l the pivot-screw is entirely disi pensed with, the spring being so formed and arranged as to perform the function of a,V

To this end both members 9 and l0 of the body of the l mounting and the nose-guard lever are propivot as well as of a spring.

vided with alining pertoratioiis of a diameter suiiicient to receive the coiled por- 'lhis portion ot the tion 14 of the spring. spring extends entirely through the three perforations and its bent ends engage, respectively, the nose-guard lever and the body of the mounting, as in the previous case, and y thus retain the spring in place. The coiled portion oic the spring iits the perforationsf closely, and is maintained in place by the ends of the spring, and it thus acts in substantially the same manner as a solid pivot l to prevent lateral movement of the noseguard lever between the body members 9 3 opening into operative engagement with the and l0.

ln the modilied form shown in F ig. 5 a thin tubular sleeve 17 is inserted loosely between the spring and the perforations, this i sleeve acting as a pivotal bearing for the iiose-guardglever and being held in place by l the ends of the spring.

l claim l. An eyeglass mounting comprising a body having two separated members, a nosey `coiled portion lying in said perforation and bent ends lying, respectively, above and below one of said members so as to secure the spring in said perforation.

2. An eye-glass mounting comprising a body having two separated members, a noseguard lever embraced and pivotally supported between said members, the lever and one of said members having alining perforations, and a spring connecting said body and said lever and having a coiled portion lying in bot-h said perforations and bent ends lying, respectively, above and below one of. said members so as to secure the spring in said pertorations.

3. An eye-glass mounting comprising a body having two separated members, a nosethrough all ot' said perforations and bent ends lying, respectively, above and belowi said members, and a bearing-sleeve loosely surrounding said coiled portion of t-he spring and affording a pivotal bearing for the noseguard lever.

5. An eyeglass-mounting comprising a body having two separated members, a noseguard lever embraced and pivotally supported between said members, one of the inenibers having a spring-receiving opening coni y.,

centric with the pivot-al axis of the lever; and a spring connecting said body and lever, the spring having an intermediate coiled portion lying in said opening, an

end extending from the outer end of the .Y f

the opening and against longitudinal movel ment therefrom.

6. An eyeglass-mounting comprising a f nose-guard lever, a body upon which said lever is pivotally mounted, the body being provided with a spring-receiving opening' concentric with the pivotal axis ot the lever; and a spring having an intermediate coiled portion lying in said opening, one end` ot the spring being iixed against rotative movement, and the other end extending, from the outer end of the opening, to and into c-perative engagement with the noseguard lever.

7. An eyeglass-mounting comprising a nose-guard lever, a body upon which said lever is pivotally mounted, the body being provided with a spring-receivingl opening, and a spring connected at its respective ends with the body and the lever; the spring having an intermediate coiled portion lying in said opening and supported by engagement ot the outer surface of the coiled portion with the walls of the opening.
